Milage keeps decreasing with every tank...
 

My MPG seems to be fluctuating a lot, despite my trips being the same - I once hit 41-42ish, but my last fill was barely 35...its weird, because the trip is generally the same - from my house, its about a mile or two (engine warms up in this time), and then a lot of hills to school...

The hills I drop to neutral, generally 40-45ish at the peaks and a max of 60 on the downhill, then rev match (or at least try to, no tach...yet) and let the speed bleed off to around 40ish when I get to the top of the hill, but sometimes lower, as the car doesn't force itself to downshift until I drop below 30mph.

Anyways, maybe its just me or the weather, as its getting colder now...and if its me, the scanguage should come in tomorrow.

:)

I just brought it in for an inspection and oil change today as well.

And how do I get the sig? Or does that just come with time...

My mpg is dropping, too. How's the weather out there? I saw my mpg drop off since the weather started getting cooler.

Its a little cooler, sometimes by like 30 or so degrees., but generally somewhat close (i'm guaging this by the fact that back then I wore shorts and tshirts, now I wear jeans and sometimes hoodies...)

Have they switched over to the winter blends yet for gas? That can be a factor in your decrease in fuel economy.

In the top right of this website when you are logged in it says "Welcome Minger" and right below that there is a link that says "Private Messages." If you click on "Private Messages" you will be taken to a page where there is a Control Panel on the left of the page. You will see some helpful links under the control panel that will let you edit your custom title and signature and some other stuff. Took me awhile to figure this out. :P

My mpg fluctuates a lot too. Being colder is definitely part of the culprit. The other thing could be that sometimes when I fill up my tank it does not fill all the way to the very top... and other times it does. So maybe this is also happening with you. Do you fill up at the same station or even same pump when you refill?

no, not that sig - I know where the forum sigs are - I meant one like yours where it shows the mpg and stuff =]

For the last few, I've used the same pump, as one of the ones next to it never seems to stop...but maybe thats the one that helped me get my 42 mpg that one time - overfill, and then use the one that would stop where it regularily does...

And I don't know if they've switched over to winter blends yet

I think you can get the MPG signature picture in your gaslog or garage somewhere, should display the code for you somewhere around there...

It's prolly just the weather...you could throw some acetone in there and "prove" how it doesn't work...I'm just being mean though.

Na, I'll pass on that. Scanguage is in, gonna go driving later...maybe =]

I just wish I had a 5th gear in this automatic...makes me sad, because sure, its fine for driving around here, but the highway...I'm up around maybe 3000-4000rpm and its loud (never get my car up there to start with)

Trade it in for a stick VP? I test drove one of them back in 2005, nice car.

Its not really my call - its my parents' car. Next year though, my brother starts driving and whatnot, maybe I can convince them to let me get something else...

And they don't like the idea of me driving stick, but I wouldn't mind learning - before trying to save gas, automatic would just put me to sleep.

\I doubt they'd go for a CRX or something that old though (they don't like the idea of it breaking down and repair costs), but maybe something like an older civic hatch or an integra (the integra would be like lowering my standards, but I love the car =])

I had to make the choice when I turned 17 of having my mom buy me the 2005 VP or paying for my own crx, I chose the crx, :)

Have them wait and get the new hybrid coming out in 2009 from honda, should be interesting.

The CRZ? It looks a little funky, but I'd probably buy it. I just wish Honda could sell the European civics over here, or soemthing that was just lighter.

Nah, not the CRZ, Honda announced a few years ago they were bringing out a 4 door with insight-like or better mileage in 2009, or something like that.

Oh. I've heard the rumors of a new CRX...but a 4 door insight = either a CRX...or prius...and i hope not the prius (I don't know why, but despite looking alike, the prius is ugly)...

I think I figured it out! The last week, they've been calling me into work...and its a 3 mile drive - scanguage told me I get 33mpg if I take the route with hills, 31 without hills.

Not warming up sucks =[

Ebh?

ebh? wha?

well, I've been doin that 3 mile drive twice every day for the past week on top of my regular 5-6 mile drives to school. I say i need a roadtrip to get my numbers up :)

Engine block heater I meant, but if you're at school then whatever...

With a commute that short you might as well bike, it's tons of fun...

Yeah, bike if you can. Especially during these glorious fall days!! you get great mpg when you bike. Something like 5000mpg. (You have to take into account the extra home fuel used to cook more food since you use up more calories when biking.)

The problem is - its not a flat road. If so, I wouldn't mind biking - previous years, I've biked regularily to the high school and work (7ish miles or so either way)

Its more that...the hills here absolutely suck - I have to walk up them once getting about halfway up...or I just need to be in better shape...hmm.

Don't give me ideas! :P

Get in better shape or get some easier gearing for the hillz, :p

I was riding with a group of fairly solid riders this summer. The bike I was using didn't have a granny gear. Everyone else spinning up the hills nice and slow at a good high RPM and I'm struggling to maintain 8mph. By the end of the summer I was able to tackle the big hills and manage to keep from falling under 8mph. (any slower than that and the RPMs get too slow and then it sucketh the big time.) It was challenging and all, but biking is fun; the hardship of hills seems worth it to me.

Hmmm...tempting. Only other thing I can think of that would stop (or make me getinto freaking good shape) is that usually I have a break in the day - sometimes 3-4 hours, so I go home...either I toughen up and get in shape or die on thew a...:p

Maybe in the spring...but II just keep postponing working out :/

Start now!

Join the club minger! My driving improves and my mileage goes down. What fun! I want to know how come some people have a 90 day running average. Not that I have anything to show off.

A few things to check when your mileage starts dropping would be: Air pressure in the tires, brakes dragging check for warm wheels and rims, Oil getting close to the end of its life needs changing, exhaust pipe soot buildup from faulty injection, fuel leak, colder temperatures, low engine temps from faulty thermostat - to name just a few things.

Just got inspection and oil changed...the rest should be decent as its still a fairly new car, psi is 43ish cold

one more question - if the scanguage gives me the current mpg as around 100+ when in neutral, and 9999 when in gear when coasting, should I continue to coast in neutral or in gear?

The coasting question is a difficult one...you will use no fuel coasting in gear (on a manual) but some coasting in neutral. I usually cost in gear to a stop and neutral when I don't want to slow down.

Weird. You'd think they'd have found a way to shut it off when in neutral, but then again, I might just not know what I'm talking about. Which I don't.

I guess I'll AB it with my first trip today and when I go back to school in half an hour...which ones higher.

You can always shut it off yourself, :p

I know, but I can't get a minute out of it - theres only like three places where I can do that (one pulling into work, about .7 of a mile, another down a hill to a light thats usually red, and one pulling into my neighborhood, which means I have to turn fast and the neighbors don't like it :P)

Well then, guess you'll have to bike.

What you see in neutral is the minimum fuel it takes to keep the engine turning over at idle - end in gear it doesn't take any fuel to keep it turning over becuae the engine is being turned over by the transmission - wheels - energy in the car . . . thus saving even more fuel but slowing you down a little. So coast in neutral when you do not want to slow down and coast in gear when you want to slow down or need to limit your down hill speed. Cool that it can figure out that the injectors are shutdown when in gear - my Scion doesn't do that and I end up with lower than actual MPG readings whenI engine brake a lot.

Cool, never thought about that.

Its just that the first time I saw 9999 i was like 'LOLWTF?' :D

My VX goes faster in gear than in neutral when coasting! Does it also use less fuel in gear!?

No, it only uses no fuel when engine braking.

Wait, in gear it's using no fuel? For real? I've been wasting fuel this whole time?!?!?!?!?

Let me get this straight. I put it in gear, but don't touch the gas pedal. I'm using no fuel?!?

Only if you're engine braking...if you're at a low enough rpm and not engine braking the car will be injecting fuel.

Buy a freaking supermid already.

Hmm... yeah, tires first. Then maybe supermid. You'll have to install it for me tho. :p

On your car, when your throttle is closed (foot off of the pedal) and the engine rpm is above about 1500 rpm, the ecu doesn't enable the injectors and it doesn't use any fuel. When your engine rpm gets to about 1500, then the injectors are used to bring the engine to a smooth idle.
